A senior official of UNICEF has called for children vulnerable to violence, exploitation, abuse and neglect to be supported, saying no country is immune to violations of a child's right to protection.

UNICEF Child Protection chief Susan Bissell said Friday that the world should shed more light on children facing difficult circumstances such as physical and mental abuse, commercial sexual exploitation, trafficking, child labor, child marriage and armed conflicts in which children are recruited as soldiers.

"What's really interesting, I think, about child protection is that there is no country in the world that doesn't have issues," Bissell said.
